In the scheme of each contactor there is one set of closing contacts built in the control module coil. Due to the presence of the push button control station it allows you to build a simple control scheme.

The design of the contactors allows you to mount two additional consoles in any set at the same time.

The indicator of contact position of the system is placed on the outer panel of the side cover. This allows you to check the status of the contact system without disassembling the contactor. It saves working time.

Availability of indication (notches made at the factory) on the contacts allows to determine their degree of wear.

The top cover is fastened with screws with locks. This eliminates the spontaneous loosening. Therefore, KTI Series contactors can be installed in places where continuous working vibration is present.

Use of standard socket wrench to change the contact pressure of the contact system and check the effect of the contact system.

Contact parts are made of silver-based composites, to reduce the contact resistance while increasing the temperature.

Factory assembled reversing contactor is supplied with factory buses and mechanical interlock. Contactors are mounted on two metal rails, that ensures high rigidity of the structure. KTI reversing contactors are a separate group in the assortment of the company.

Enhanced design of control coil allows its dismantling without tools (by pressing the latch in the contactor casing).
